Forgiveness keeps a critical position in the teachings of ACIM. Unlike traditional notions of forgiveness, which frequently include pardoning the observed wrongdoings of others, ACIM's forgiveness is a process of issuing judgments and issues used against oneself and others. It is just a acceptance that the perceived sins and problems are grounded in the illusions of the vanity, and through forgiveness, one can see beyond these illusions to the natural purity and divinity in most being. ACIM teaches that forgiveness is just a way to inner peace and the main element to undoing the ego's hold on tight the mind.

The Workbook for Students, comprising 365 instructions, is a practical information designed to lead the student via a major process. Each training centers around a particular concept, guiding the practitioner to use the teachings inside their everyday lives. The instructions protect a wide variety of issues, including notion, forgiveness, enjoy, and the type of reality. The repeated nature of the acim is intentional, reinforcing the proven fact that consistent practice is required for the transformation of consciousness.

A Course in Wonders also presents the concept of the Holy Nature as helpful tips and intermediary between the egoic mind and the true Self. The Sacred Nature is portrayed as a supportive and nonjudgmental inner style that helps individuals reinterpret their activities and perceptions in stance with truth. ACIM encourages a constant dialogue with the Holy Soul, seeking advice and wisdom in all facets of life.

One of the distinct facets of ACIM is their usage of Christian terminology and symbolism, that might originally lead some to sort it as a Religious text. However, the program transcends traditional spiritual boundaries and addresses to the general maxims of spirituality. ACIM encourages persons from all faiths (or none) to set about a journey of self-discovery and internal transformation, focusing particular knowledge around dogma.
